We are getting better with time. We have won over many incurable diseases, we have replaced humans with machines where we have been risking our lives.
Our quality of life has also gotten better, we have replaced the horse cart to cars. Most of our country has electricity, the fight against malnutrition is still on.
There is no absolute way of seeing our world. We still have got numerous things waiting to be fixed. As a civilization, we have gone through grind, build, fall, learn and repeat. Being pessimistic about everything in this world is not the solution.
Lotus flowers in the swamp, gold goes through multiple molding before becoming a piece of jewelry. This world is a broken place, which also means we have got so many opportunities to work on and make this world a better place.
Imagine what dreamers would have contributed to the world without being an optimist and not giving up easily.
